Description

technical field [0001] The invention relates to the field of shock absorbers, in particular to a variable inertia variable damping shock absorber. Background technique [0002] With the advancement of technology, inertial devices have been gradually applied to the field of vibration reduction / isolation, such as vehicle suspension, seat suspension, train suspension, building vibration isolation and power systems, etc. However, the traditional passive inertial capacity device cannot meet the needs of different working conditions, so it is necessary to study the variable inertial capacity device. However, the ideal inertial device itself does not consume energy. In order to ensure timely energy dissipation, the variable inertial device must be equipped with a damping unit, and different working conditions have different matching requirements for inertial capacity and damping, so a variable damping unit is required. Considering the low energy consumption, fast response characte...

AI Technical Summary

Problems solved by technology

Considering the low energy consumption, fast response characteristics and high yield stress of magnetorheological fluid devices, the use of magnetorheological fluid technology can reduce the energy consumption of active variable damping. Damping shock absorbers are very important to improve the effect of vibration reduction / isolation in different working conditions, but there are still few studies in this area, and it is very important to propose a new type of variable inertia variable damping shock absorber
